Meeting Announcement – Pat Brown – September 10, 2014

TOPIC: There are few things more confusing in the audio marketplace than amplifier and loudspeaker performance specifications. Their origins are often obscure. Their validity is often questioned. While the likelihood is high that there will someday be meaningful, universally-recognized Standards for these metrics, in the meantime audio engineers must specify and deploy loudspeakers and amplifiers. The “Common Formats” have addressed the problem by providing real-world, defensible methods determining key loudspeaker and amplifier metrics for use by sound system designers. The Common Loudspeaker Format (CLF) has become the most widely used data format for room modeling programs. The Common Amplifier Format (CAF) builds upon it. Together they give the sound system designer everything needed to deploy loudspeakers and amplifiers. Pat Brown will present the major tenets of each.
